In. the pastithas, been the practice of shoe,- l makers or cobblers tohold a shoe on a last by of a strap or sling passing over the shoe andlooped d to receive the cobblers foot. This requires that the cobbleralways have a foot in the. sling while working on a shoe, which pre- 30,vents freedom of movement and is generally a clumsy method. of. holdingthe shoe. With our improved vise th c bble s not v to keep his foot in astrap.

In terms of broad inclusion, the shoe vise embodying our invention ismounted on a shoe last supporting stand. The vise comprises means forholding a shoe on the last, and means for fastening the in shoe holdingposition. The shoe holder is preferably a pivotally mounted arm having astrap for engaging the shoe, so that when the arm. fastened down thestrap is tightened against the shoe.

In greater detail, and referring to Figures 1 and 2 of the drawing, ourshoe vise is mounted on the ordinary stand 2 which supports a shoemakerslast 3. The vise comprises a bracket 4 having a sleeve portion 5embracing the stand. The mounting sleeve has a hinged section and theparts are clamped about the stand by any suitable means, such as ahinged bolt and lever nut 5. The bracket extends upwardly and rearwardlyand terminates in a forked portion 7.

A shoe holding arm 3 is pivotally mounted on the bracket on a pin 9between the legs of fork I. This arm is yokeshaped, and in the shoeholding position shown in- Figure. 1, fingers lilrof the yoke projectforwardly about the sides. of a shoe H- on the last. The yoke. fingers.have. slots t2: for carrying a strap. l3 extending across. the

.wardiy. below the shoe. sole, so that the upper surface of the shoe isleft substantially clear for working purposes. Strap it of" courseextends across the top, butthatis. also. true at straps prov is movablefrom itsv shoe viously used. Arm 81 holding positionlto a retractedposition extending rearwa-rdlyl, as. shown by. dotted lines; in Figurei. In this. retracted: position the arm is out; or the way, and the shoeis free forren'ioval from the last.

Means are: also provided for urging arm 8- into retracted position, so.that as soon as the arm.

is released it swings back out of the way For this purpose. a spring lzi ispreierablycoiled; about the pin with one end anchored in the fixed;pin and the other and fastened to. the arm. end it. or the arm is.preferably bifurcated as shown in Figure 2, to. give a widerbearingtoallow a central placing of spring M. fiuitable stops or lugs H:on the arm and bracket serve to limit the in retracted position.

Means are provided for clamping arm 8 down in shoe holding position totighten strap l3 against the shoe. For this purpose a hooked-shaped cami8 is pivotally mounted by a pin is extending between fork l of thebracket, and is adapted to engage a pin 2! extending between the sidesof bifurcated arm portion 16. Face 22 of the cam is designed to applydownward pressure on arm 8 when the cam rotates ahead; and the hook ofthe cam extends forwardly so that the cam rides off pin 2! to free thearm when the cam rotates backwardly.

Means are provided for actuating the cam. As

best shown in Figure l, a lever 23 is also fixed on pin 19 and extendsforwardly to provide an operating handle or knob M conveniently arrangedbelow the last. The lever is movable between clamping and releasepositions; the latter being indicated by dot and dash lines in.Figure 1. .An unbalanced spring 26 is connected between the bracket andlever and serves to urge the lever.

into one or the other of its positions as the spring passes over thepivot center; Stops or lugs 21 on the lever and bracket serve to limitmovement of the lever; and the upper limit is set so that pin 2| clearsthe end of cam l8 to allow arm 8 to.

be brought down.

In the operation of the vise, arm 8 is first brought down and lever M isthen pushed down to engage cam lt-with pin 25. Once engaged, arm 8 isautomatically held, and further downward movement of the lever tightensstrap it against the shoe by reason of thecam action. After the straphas been tightened, arm 8 stays in the clamped position because of thefriction between cam l8 and pin 21, and also because of the tension inspring 26 tending to hold lever 23 down. Cam surface 22 need not besteep, since a small movement here results in a large movement at theend of the arm. Thus there is little tendency of arm pin 2! to move backout on the cam.

When it is desired to free the shoe it is only necessary to tln ow lever23 into its up position, thus releasing arm 83 and allowing the latterto swing back into its retracted position. With 8 out of the way, theshoe may be worked on Without being clamped down, or the shoe may beremoved.

While we have shown the pivot mounting of arm 8 at the heel side of thelast, it is understood that the Whole arrangement may be reversed toposition the bracket under the toe.

Figures 3 and l show a modified construction comprising a strap 3!connected to a yokedshaped arm having fingers 32, one of which extendsinto a lever 33 terminating in a handle arm in a selected position. Forthis purpose a disc or segment 39 is formed on the bracket and isprovided with notches for receiving a springpressed dog ii actuated by abutton 42 at the end of the handle.

By this simple arrangement the lever may be pressed down and locked whensufficient tension has been put in the strap.

When the stand is turned around for the cobbler to Work from the heelend of the shoe, the

- yoke arm is thrown over to the opposite side,

as indicated by dotted lines in Figure 3, to tension the strap from theopposite angle. The action of the hold down strap is thus substantiallythe same as the slings now used, except that the foot of the cobbler isleft free.

The yoke-shaped shoe holding arm is so pivoted that the strap pulls downat substantially the same angle for either side of the stand; and theyoke finger length'is such that the strap automatically clears the shoewhen the arm is thrown over. When the device is not in use the arm andstrap hangdown in retracted position alongside the stand where they arecompletely out of the Way.

We claim:

1. The combination with a shoe last and supporting stand, of a shoe visecomprising an arm 2. The combination with a shoe last and supportingstand, of a shoe vise comprising an arm pivotally mounted for movementbetween operative positions extending from opposite sides of the. stand,a strap on the arm for engaging a shoe on the last in either position ofsaid arm, and means for holding the arm in either of its oppositelyextending positions.

3. The combination with a shoe last, of a shoe vise comprising a strapfor straddling the instep of a shoe on the last, the depending ends ofthe strap slanting forwardly in one position to draw the heel of theshoe against the last and slanting rearwardly in another position todraw the toe of the shoe against the last, and means for tensioning thestrap in said positions.

4. The combination with a shoe last, of a shoe vise comprising a strapfor straddling the instep of a shoe on the last, the depending ends ofthe strap slanting forwardly in one position to draw the'heel of theshoe against the last and slanting rearwardly in another position todraw the toe of the shoe against the last, and means including an armpivoted about an axis lying below said instep and movable from one sideto anotherof said axis for tensioning the strap in its forwardly andrearwardly slanting positions.
